My invention relates to pressure accumulators for gases or liquids.

' The pressure accumulators of the type described in the patent application Serial No.

" 371,948, Patent No. 1,817 ,226, August 4, 1981,

have proved satisfactory under normal conditions'; that means pressure accumulators which consist of an external pressure-resisting container and an internal container which need be gasor liquid-tight only, and

which transmits the pressure to the external container through the intermediary of a viscous tightening substance. Now, frequently speclal requirements have to be met, how-.

ever, by these accumulators as to the height of the pressure and to the gases or liquids to be stored up therein, which requirements can not be completely complied with by this construction. My invention has therefore for its object to so improve pressure accumula tors of the above type that all conditions can be met. This object is attained primarily by a plurality of nested internal containers being provided, made from metal, concrete or the like, the intermediate spaces existing between the largest thereof and the outer pressure-resisting container being filled with a viscous tightening substance which acts as the agents to be stored and to the height of the pressure to be taken up,- the tightening substances inserted between the individual containers may possess different viscosity. It is further possible to dispense with the proper internal containers and to cover the inner surface of the external container successively with several layers of the tightening substance, the external film of each layer after applicationbeing prepared in such a manner by a suitable treatment, such as applicathat the layer forms, so to speak, an internal container which acts exactly in the same man ner as a normal container made from metal,

Under suitable geological conditions the strengthening of the external container can be replaced by rock pressure.

In order that my invention may be more 350 readily understood, several embodiments of pressure-resisting container a.

pressure-transmitting means. According to the same areillustrated by way of example in the accompanying drawing, in which Figure 1 is a horizontal section through a pressure accumulator" forming the first embodiment'of my invention.

'Figure2 is a similar section of another embodiment. i Figure, 3 shows the "third embodiment, while i V Figure 4 illustrates the arrangement ot new pressure container in a rocky country. Asto be seen from Figure 1, the pressure accumulator is composed for example of seVQ eral spacedly nested internal containers b 5 which are disposed within an external 7 l y The latter. may be strengthened for example bytie bolts 6 situated in three planes and secured by nuts,

g. )The spaces'existing betweenthe contain ersbfi bfland a are filled with viscous tightening-Inaterial denoted by 0 and 0 which 'materials' maypossess difierent viscosity; to

meet all requirements. V I .Ifurther proposeto have the internal con-f ta-iners bf," b? themselves entirely, dispensed with, by applying to the inner surface of the outer container 1;, first a layer a of viscous tightening material and so preparing the surface thereof by a proper painting, a metal" ooating or infanyother suitable manner,.that so to speak a container 6 is produced to which viscous tightening material 0 is then applied, the surface of which is likewise to be treated in the described manner, whereby" the internal container b is formed. In this .way a great number of layers can be formed which together afford a very satisfactory "tightening elfect, the pressure being again taken up by the external container 'a. tion of a painting or 1n any other manner,

As tob'e seen from-Figure 2, the containers may be strengthened also by tie rods '7 the ends of which carry-wood thread hand which are likewise situated'in three planes. Finalwith nuts 9, while the shell wall, if'the container has cylindrical shape, is so r'e-inforced I by metal rings or wire coils n that it iscapable to resist to the radially acting pressure. In rocky countries the strengthening of the external containeror the container itself may be dispensed with, as illustrated in Figure 4.

5 Here the rock a itself forms, so to speak, the

' externalcontainer in which'one or more inner containers 6 b are embedded, with suitable tightening substances 0 between them. It is particularly inthisembodiment of my improved pressure accumulator that the above described method can be employed with particular advantage, because it may be difficult to build inthe internal containers.

Therefore, after the proper cavity has been .ed with a viscous material the surface of which is then preparedbya suitable painting, metal coatingor the like, whereupon the in the rock, the walls thereof are coatternal containers, layers of viscous'pressure transmitting tightening material intermedi next. tightening layer is applied thereto. 7 4

This operation may be; repeated until the desired internal structure is attained which then again comprises several containers with intermediate tightening layers.

' inner structure depends upon the prevailing geographical and geological,,conditions; 'modifications of different kind may therefore be. provided if required without deviating from the scope of my invention.
